Alien Kryptonite (ft. COVENANT, Spacetime, Atoms 99.9999% Science)

The Xenomorph, better known just as Chimeras (which literally translates to "alien form") or the Alien, are an extraterrestrial, endoparasitoid species with multiple life cycles, possibly originating from another planet. One of the deadliest of all known alien species, these creatures need a host organism in order to reproduce. The appearance of the Xenomorph varies depending on its host. But as ferocious as they are, does a weakness lie within them? And if so, could this Xenomorph-Kryptonite render them utterly, powerless?
